Atomic sensors, which make use of the inherent precision of atomic energy levels, are moving from the laboratory, where they have pushed the limits of precision measurements [1]}, [2]}, [3]}, to applications in the field, where the requirements are shifted toward portability, reliability, and integration [4]}. Successful miniaturization of vacuum technology for cold-atom sensors will impact a wide range of applications including gravimeters, accelerometers, gyroscopes, clocks, magnetometers, and gravity gradiometers.
